Abstract

The invention provides a release building structure for hydraulic engineering. The release building structure for hydraulic engineering comprises a foundation and a downstream channel, wherein a spillway is arranged at the upper end of the foundation and spillway side walls integrated with the spillway are arranged at the left and right ends of the spillway; a first slope section is connected below a vertical section; a second deflecting flow bank is fixedly connected to the middle part of a second slope section; and the tail end of the second slope section is connected to a stilling pool through an arc-shaped section. Each group of first step block units which are uniformly arranged front and back vertically and e ach group of second step block units which are uniformly arranged front andback vertically are arranged in a spaced manner left and right, so that a generated jet flow and a rolling water flow generated by eddy with horizontal axis are contacted when the water flow passes through the first step block units and the second step block units every time to play a shearing role, so that contacted water flows have turbulent fluctuations to enhance the aerifying effect and diffusion of air bubbles in the water flows is enhanced.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, in particular to a water conservancy drainage building structure. Background technique [0002] Water release structures are hydraulic structures used to discharge excess water, sediment and ice. The discharge structure has the function of safely draining flood water and emptying the reservoir. It acts as a fire door for the operation of reservoirs, rivers, channels or forebays, and can also be used for construction diversion. Spillways, overflow dams, scuppers, and tunnels are the main forms of drainage structures. Those combined with the dam are called dam body discharge structures; those located outside the dam body are often collectively referred to as shore discharge structures. [0003] The spillway is used to vent the flood that cannot be accommodated by the planned storage, to ensure the safety of the dam body or an overflow discharge structure with breast wall wa...
